Comments:
-!- FUNCTION: The UvrABC repair system catalyzes the recognition and
processing of DNA lesions. A damage recognition complex composed
of 2 uvrA and 2 uvrB subunits scans DNA for abnormalities. Upon
binding of the uvrA(2)B(2) complex to a putative damaged site, the
DNA wraps around one uvrB monomer. DNA wrap is dependent on ATP
binding by uvrB and probably causes local melting of the DNA
helix, facilitating insertion of uvrB beta-hairpin between the DNA
strands. Then uvrB probes one DNA strand for the presence of a
lesion. If a lesion is found the uvrA subunits dissociate and the
uvrB-DNA preincision complex is formed. This complex is
subsequently bound by uvrC and the second uvrB is released. If no
lesion is found, the DNA wraps around the other uvrB subunit that
will check the other stand for damage (By similarity).
-!- SUBUNIT: Forms a heterotetramer with uvrA during the search for
lesions. Interacts with uvrC in an incision complex (By
similarity).
-!- SUBCELLULAR LOCATION: Cytoplasm (By similarity).
-!- DOMAIN: The beta-hairpin motif is involved in DNA binding (By
similarity).
-!- SIMILARITY: Belongs to the uvrB family.
-!- SIMILARITY: Contains 1 UVR domain.
